종래 냉장고의 도어 스위치는 도어 판넬에 보턴형 도어 스위치를 설치하여 도어를 열고 닫음에 따라 냉장실 내부의 램프가 "온" "오프"되도록 한 방식과 냉장고의 중간부 앞 판넬에 보턴형 도어 스위치를 설치한후 도어 샤시에는 누름 스위치를 설치하여 냉장고 도어의 열고 닫음에 따라 이들이 한조를 이루어 냉장실 램프등을 "온" "오프"시킬 수 있는 방식을 사용 하였다.The conventional door switch of the refrigerator has a button-type door switch installed in the door panel so that the lamp inside the fridge is "on" and "off" as the door is opened and closed, and the button-type door switch is installed in the front panel of the middle part of the refrigerator. The door chassis was then equipped with a push switch to open and close the door of the refrigerator, and they used a way to turn the fridge lamps on and off.

그러나 이와 같은 방식은 냉장고의 외부에 돌출된 누름 스위치를 설치하여야 되고 또한 도어 스위치의 설치장소등이 제한되어 있어 외부 디자인이 제한되는 단점이 있으며 또한 기계적 접점을 사용하므로써 고장의 우려가 많고 원가 상승등의 요인이 되는 것이었다.However, in this type of system, it is necessary to install a push switch protruding from the outside of the refrigerator, and the installation location of the door switch is limited, which limits the external design. It was to be a factor.

본 고안은 이와 같은 점을 감안하여 냉장고의 냉장실과 냉동실 내상에 리드 스위치를 설치하고 도어를 열고 닫을 때 냉장고의 내상과 맞닺는 냉동실 및 냉장실의 도어 판넬상에는 마그네트를 설치하여 마그네트와 리드 스위치간의 거리가 가깝고 멀음에 따라 리드 스위치가 "온" "오프"되는 것을 이용한 냉장고의 도어 스위치로써 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.In view of the above, the present invention installs a reed switch in the refrigerator compartment and the freezer compartment of the refrigerator and installs a magnet on the door panel of the freezer compartment and the refrigerating compartment that matches the inside of the refrigerator when the door is opened and closed. As the door switch of the refrigerator using the reed switch "on" "off" in close and far as described in detail by the accompanying drawings as follows.

제1도는 본 고안이 설치된 냉장실의 요부 확대 단면도로써 냉장실 도어 판넬(7)과 마주보는 냉장실 내상(8)에 걸림 지지구(1b)가 양측에 설치된 설치함(1)을 내삽할 수 있는 설치공(4)과 삽입공(9)을 형성하여 설치함(1)이 설치공(4)에 내삽될때 빠지지 않도록 삽입공(9)에 걸림 지지구(1b)를 끼워 맞추도록 구성한다.1 is an enlarged cross-sectional view of the main part of the refrigerating chamber in which the present invention is installed, and an installation hole capable of interpolating a mounting box (1) in which a locking support (1b) is installed on both sides of the refrigerating chamber inner panel (8) facing the refrigerating chamber door panel (7) (4) and the insertion hole (9) is formed to fit the locking support (1b) to the insertion hole (9) so as not to fall out when the installation box (1) is inserted into the installation hole (4).

이때 설치함(1)의 내부에는 리드스위치(5)를 내삽한 후 설치함(1)에서 리드 스위치(5)가 분리되지 않도록 에폭시수지(3)로 모울딩하여 구성한다.At this time, after inserting the reed switch 5 into the inside of the installation box 1 is configured by molding with epoxy resin 3 so that the reed switch 5 is not separated from the installation box (1).

그리고 냉장실 도어를 닫을 때 리드 스위치(5)가 내삽된 설치함(1)과 마주보는 냉장실 도어 판넬(7)상에는 걸림 지지구(2b)가 양측에 형성된 설치함(2)을 내삽할 수 있도록 삽입공(9')을형성한 후 설치함(2) 내부에는 마그네트(6)를 내삽하되 설치함(2)과 마그네트(6)가 분리되지 않도록 에폭시수지(3')를 모울딩 하여 구성한다.When the refrigerating compartment door is closed, the reed switch (5) is inserted into the interlocking compartment (1) facing the interlocking compartment (7) so that the interlocking compartment (2) having interlocking supports (2b) can be inserted on both sides. After forming the ball (9 ') is installed by inserting the magnet (6) in the installation (2) inside the molding (2) and the magnet (6) is formed by molding the epoxy resin (3') to be separated.

이때도어 판넬(7)의 설치함(2)에 설치된 마그네트(6)과 내상(8)에 설치된 리드스위치(5)는 문을 닫았을때 최소간격이 되도록 하여 리드스위치(5)가 "온"되고 최소 간격을 벗어 났을때 즉 도어를 열게되면 "오프"되도록 한다.At this time, the magnet 6 installed in the mounting box 2 of the door panel 7 and the reed switch 5 installed in the inner box 8 have a minimum distance when the door is closed so that the reed switch 5 is turned on. And "off" when the door is open beyond the minimum distance.

이와 같이 냉장실에는 마그네트(6)가 내삽된 설치함(2)과 리드스위치(5)가 내삽된 설치함(1)으로 한조의 도어 스위치를 구성하고 냉동실에도 이와 같은 방법으로 또 다른 도어 스위치를 구성한다.Thus, a set of door switches is composed of a cabinet (2) in which a magnet (6) is inserted in the refrigerator compartment and an cabinet (1) in which a reed switch (5) is inserted. do.

그리고 설치함(1)에 내삽된 리드스위치(5)는 제2도 의 냉장실 도어스위치(SW2)에 연결하고 냉동실에 설치된 또 다른 리드스위치는 제2도의 냉동실 도어 스위치(SW1)에 연결 구성한다.And the reed switch 5 inserted in the installation box (1) is connected to the refrigerator door switch (SW 2 ) of FIG. 2 and another reed switch installed in the freezer compartment is connected to the freezer door switch (SW 1 ) of FIG. do.

제2도는 본 고안의 회로도로써 일측이 접지된 도어스위치(SW1)의 타측에는 저항(R1)을 통하여 전원(Vcc)이 인가됨과 동시에 저항(R2)(R3)과 콘덴서(C1)를 통하여 트랜지스터(Q1)의 베이스를 연결하여 구성하고 트랜지스터(Q1)의 에미터에는 보호용 다이오드(D1)가 연결되고 전원(Vcc)이 인가되는 릴레이(RL1)를 연결 구성한다.2 is a circuit diagram of the present invention, while the power supply Vcc is applied to the other side of the door switch SW 1 having one side grounded through the resistor R 1 , and at the same time, the resistor R 2 (R 3 ) and the capacitor C 1. ) configuration by connecting the base of the transistor (Q 1) through and has a protective diode (D 1) connected to the emitter of the transistor (Q 1) and configured power (Vcc) to the relay (RL 1) that is connected.

이때 릴레이(RL1)의 릴레이 스위치에는 교류전원(AC)이 인가되는 팬모터(12)를 연결한다.At this time, the fan switch 12 to which the AC power AC is applied is connected to the relay switch of the relay RL 1 .

그리고 일측에 전원(Vcc)이 인가되는 도어 스위치(SW2)의 타측은 저항(R4)을 통하여 접지시킴과 동시에 저항(R5-R7)과 콘덴서(C2)를 통하여 트랜지스터(Q2)(Q3)의 베이스를 연결하며 예미터가 저지된 트랜지스터(Q2)의 콜렉터는 트랜지스터(Q1)의 콜렉터와 연결되게 구성한다.The other side of the door switch SW 2 to which the power supply Vcc is applied to one side is grounded through the resistor R 4 , and at the same time, the transistor Q 2 is provided through the resistors R 5- R 7 and the capacitor C 2 . The collector of transistor Q 2 , which is connected to the base of Q 3 ) and the emitter is blocked, is configured to be connected to the collector of transistor Q 1 .

또한 콜렉터가 접지된 트랜지스터(Q3)의 에미터에는 보호용 다이오드(D2)가 연결되고 전원(Vcc)이 인가되는 릴레이(RL2)를 연결하며 릴레이(RL2)의 릴레이 스위치에는 교류전원(WC)이 인가되는 램프(13)를 연결하여 구성한다.In addition, the protection diode the emitter of the transistor (Q 3) of the collector to the ground (D 2) is connected and which is applied with a power (Vcc) connected to the relay (RL 2), and has the AC power supply relay switch of the relay (RL 2) ( WC) is configured by connecting the lamp 13 is applied.

이와 같이 구성된 본 고안에서 제1도는 본 고안이 설치된 냉장실의 요부 확대 단면도로써 마그네트(6)가 내삽된 설치함(2)이 냉장실 도어판넬(7)의 삽입공(9')에 걸림지지구(2b)로써 고정되어 냉장실의 도어와 함께 움직이며 리드 스위치(5)가 내삽된 설치함(1)이 설치된 내상(8)은 냉장실에 고정되어 있다.1 is an enlarged cross-sectional view of the main part of the refrigerating compartment in which the present invention is installed, and the mounting compartment 2 having the magnet 6 inserted therein is caught by the insertion hole 9 'of the refrigerating compartment door panel 7. It is fixed by 2b) and moves with the door of the refrigerating compartment, and the inner box 8 in which the installation box 1 in which the reed switch 5 is inserted is installed is fixed to the refrigerating compartment.

따라서 냉장실 문을 닫았을 때 즉, 리드스위치(5)와 마그네트(6)의 거리가 최소화 되면 리드스위치(5)는 "온" 되고 냉장실 문을 열었을 때 즉 리드스위치(5)에서는 마그네트(6)가 멀어지면 리드스위치(5)는 "오프"된다.Therefore, when the refrigerating chamber door is closed, that is, when the distance between the reed switch 5 and the magnet 6 is minimized, the reed switch 5 is "on" and the refrigerating compartment door is opened, i.e., the magnet 6 at the reed switch 5 is opened. The reed switch 5 is " off "

그리고 냉동실에 설치된 마그네트와 리드스위치도 동일한 작용을 하며 냉동실과 냉장실에 각각 설치된 리드스위치의 "온" "오프"작용에 따른 회로의 동작 상태는 제2도에서 살펴본다.In addition, the magnet and the reed switch installed in the freezer compartment have the same function, and the operation state of the circuit according to the "on" "off" action of the reed switch installed in the freezer compartment and the refrigerating compartment, respectively, will be described in FIG.

먼저 냉동실 도어가 열리고 냉장실 도어가 닫힌 상태에서는 도어 스위치(SW1)는 "오프"되고 도어스위 치(SW2)는 "온"된 상태가 되므로 전원(Vcc)이 저항(R1)(R2)을 통하여 트랜지스터(Q1)의 베이스에 인가되어 트랜지스터(Q1)는 부도통하게 된다.First, when the freezer door is opened and the fridge door is closed, the door switch (SW 1 ) is "off" and the door switch (SW 2 ) is in the "on" state, so the power supply (Vcc) is a resistor (R 1 ) (R 2 ) is applied to the base transistor (Q 1) of the transistor (Q 1) are vented through a default.

그러므로 트랜지스터(Q1)의 콜렉터에 연결된 릴레이(RL1)가 동작하지 않아 팬모터(12)는 돌지 않게 되며 트랜지스터((Q1)의 베이스에도 저항(R6)을 통하여 전원(Vcc)이 인가되므로 트랜지스터(Q3) 역시 도통하지 못하여 릴레이(RL2)가 동작하지 못하므로써 램프(13)도 점등되지 않게 된다.Therefore, since the relay RL 1 connected to the collector of the transistor Q 1 does not operate, the fan motor 12 does not rotate, and the power supply Vcc is applied to the base of the transistor Q 1 through the resistor R 6 . Therefore, the transistor Q 3 also fails to conduct, so that the relay RL 2 does not operate, and thus the lamp 13 does not turn on.

즉, 냉동실 문이 열리고 냉장실문이 닫힌 상태에서 램프(13)과 팬모터(12) 모두 "오프"되는 것이다.That is, both the lamp 13 and the fan motor 12 are "off" in the state where the freezer compartment door is opened and the refrigerating compartment door is closed.

한편 냉동실 도어는 닫히고 냉장실 도어가 열릴때에는 도어스위치(SW1)는 "온"되고 도어 스위치(SW2)는 "오프"된 상태가 되므로써 트랜지스터(Q2)의 베이스에 저항(R5)을 통하여 로우 레벨 전위가 인가되어 도통하지 못하게 되므로 트랜지스터(Q1)가 도통하지 못하여 릴레이(RL1)가 동작하지 않게 되므로 팬모터(12)는 돌지 않게 된다.On the other hand, when the freezer door is closed and the refrigerating compartment door is opened, the door switch SW 1 is "on" and the door switch SW 2 is "off" so that the resistor R 5 is applied to the base of the transistor Q 2 . Since the low level potential is applied to prevent conduction, the transistor Q 1 does not conduct, and thus the relay RL 1 does not operate, and thus the fan motor 12 does not rotate.

그러나 트랜지스터(Q2)의 베이스에는 로우 레벨 전위가 인가되어 트랜지스터(Q3)가 도통되므로 릴레이(RL2)가 전원(Vcc)이 인가되어 릴레이 스위치가 "온"되므로써 램프(13)는 점등하게 된다.However, since the low level potential is applied to the base of the transistor Q 2 and the transistor Q 3 is conducted, the relay RL 2 is supplied with the power supply Vcc so that the lamp 13 is turned on by the relay switch being "on". do.

또한 냉동실 도어와 냉장실 도어가 모두 닫힐때에는 도어스위치(SW1)(SW2)가 모두 "온"상태가 되므로 트랜지스터(Q2)가 도통하게 되어 트랜지스터(Q1)도 도통하게 되므로써 릴레이(RL1)가 동작하게 되어 팬모터(12)가 돌게 된다.In addition, when both the freezing chamber door and a refrigerating chamber door is closed the door switch (SW 1) (SW 2) are all "on" state, because the transistor (Q 2) is the conduction transistors (Q 1) also make doemeurosseo relay (RL 1 conduction ) Is operated and the fan motor 12 is rotated.

그리고 트랜지스터(Q3)는 부도통 상태가 되어 릴레이(RL1)가 동작하지 않으므로 램프(13)는 "오프"된다.Since the transistor Q 3 is in a non-conducting state and the relay RL 1 does not operate, the lamp 13 is “off”.

이상에서와 같이 본 고안은 냉동실 및 냉장실의 내상에 리드스위치를 설치하고 리드 스위치와 마주대하는 도어판넬 상에는 마그네트를 설치하여 도어의 열고 닫음에 의한 마그네트의 이동에 따라서 리드 스위치가 "온""오프"되도록 한 것으로써 종래의 외부에 돌출된 보턴식 스위치를 없앨 수 있어 냉장고의 디자인이 수려해지고 또한 고장율도 거의 없어짐과 동시에 원가 절감의 효과가 있는 것이다.As described above, the present invention installs the reed switch in the freezer compartment and the refrigerating compartment, and installs the magnet on the door panel facing the reed switch so that the reed switch is "on" and "off" according to the movement of the magnet by opening and closing the door. By doing so, it is possible to eliminate the conventional button-type switch protruding from the outside, and the design of the refrigerator is beautiful, and the failure rate is almost eliminated and cost reduction effect is achieved.
